This is a used Celestion G12H-100 woofer.   Being used, it does have some usage marks.   I have 4 available, each buy it now is for a single woofer.   All 4 are in similar condition.  These are rated at 8 ohms.   They measure between 6.4 and 6.6 ohms on my cheap meter.  Shipping calculator is for UPS but will be shipped FedEx ground.
